Configurations and controller teams
When controllers are operating in a team, configuration changes on one active controller propagate
to the other active controllers in the team.
3.7.1.1 About component keys
Each configuration component contains one or more component keys, each of which identify a
configurable property of the component.
CAUTION: Inappropriate changes to key values can result in severely degraded system
performance. For this reason, HP strongly recommends that managing the default key values be
done only by experienced network administrators and programmers who have a strong
understanding of SDN controller systems.
Information about each component key includes the current value, the default value, and a brief
description. Where applicable, the range of suggested values is also included. Component key
information
Information about the component keys are available from:
• The Configuration screen of the controller UI.
• The controller Configs REST API.
